-Module Name:
-
- ConSplitterGraphics.c
-
-Abstract:
-
- Support for ConsoleControl protocol. Support for UGA Draw spliter.
- Support for DevNull Console Out. This console uses memory buffers
- to represnt the console. It allows a console to start very early and
- when a new console is added it is synced up with the current console

-
- Routine Description:
- The following table defines actions for BltOperations:
- EfiBltVideoFill - Write data from the BltBuffer pixel (SourceX, SourceY)
- directly to every pixel of the video display rectangle
- (DestinationX, DestinationY)
- (DestinationX + Width, DestinationY + Height).
- Only one pixel will be used from the BltBuffer. Delta is NOT used.
- EfiBltVideoToBltBuffer - Read data from the video display rectangle
- (SourceX, SourceY) (SourceX + Width, SourceY + Height) and place it in
- the BltBuffer rectangle (DestinationX, DestinationY )
- (DestinationX + Width, DestinationY + Height). If DestinationX or
- DestinationY is not zero then Delta must be set to the length in bytes
- of a row in the BltBuffer.
- EfiBltBufferToVideo - Write data from the BltBuffer rectangle
- (SourceX, SourceY) (SourceX + Width, SourceY + Height) directly to the
- video display rectangle (DestinationX, DestinationY)
- (DestinationX + Width, DestinationY + Height). If SourceX or SourceY is
- not zero then Delta must be set to the length in bytes of a row in the
- BltBuffer.
- EfiBltVideoToVideo - Copy from the video display rectangle
- (SourceX, SourceY) (SourceX + Width, SourceY + Height) .
- to the video display rectangle (DestinationX, DestinationY)
- (DestinationX + Width, DestinationY + Height).
- The BltBuffer and Delta are not used in this mode.
-
- Arguments:
- This - Protocol instance pointer.
- BltBuffer - Buffer containing data to blit into video buffer. This
- buffer has a size of Width*Height*sizeof(EFI_GRAPHICS_OUTPUT_BLT_PIXEL)
- BltOperation - Operation to perform on BlitBuffer and video memory
- SourceX - X coordinate of source for the BltBuffer.
- SourceY - Y coordinate of source for the BltBuffer.
- DestinationX - X coordinate of destination for the BltBuffer.
- DestinationY - Y coordinate of destination for the BltBuffer.
- Width - Width of rectangle in BltBuffer in pixels.
- Height - Hight of rectangle in BltBuffer in pixels.
- Delta -
-
- Returns:
- EFI_SUCCESS - The Blt operation completed.
- EFI_INVALID_PARAMETER - BltOperation is not valid.
- EFI_DEVICE_ERROR - A hardware error occured writting to the video
- buffer.
